Patent JP-H10145203-A (JP)
Title: Frequency/voltage-converting circuit
Inventor: KISHINE KEIJI
IPC: H03D3/06
Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To linearly frequency/voltage-convert frequency of an input signal in wider wide range by phase-comparing the output signal of a divider and the output signal of a delay circuit, extracting DC components from the output signal outputted from a phase comparator and transmitting this to a signal output terminal. SOLUTION: A 1/2 divider 2 is connected to the signal input terminal of the post-stage, and the output signal of the divider 2 is inputted to a delay circuit 3 and an EX-OR phase comparator 4. As a result, a frequency signal inputted to the input terminal 1 is converted into a half-frequency signal (two fold in period) by a dividing circuit, and this frequency signal and the delayed signal of this frequency signal are phase-compared. That is, the delay circuit 3 delays the output signal of the divider 2 which divides the input signal to be inputted to the signal input terminal, the output signal of the divider 2 and the output signal of the delay circuit 3 are phase-compared in the phase comparator 4, and a low-pass filter 5 extracts the DC components out of the output signal outputted from the phase comparator 4 and transmits this to the signal output terminal.

Title: Single-operation detection device of synchronous generator and power generating apparatus
Inventor: TSUJI MASANORI
IPC: H02J3/38
Filed: 1994-12-20
Abstract: PURPOSE: To surely detect the single operation of a synchronous generator by a method wherein the output power of the synchronous generator is detected and, as the detected power becomes large, the frequency-fluctuation discrimination level of the output voltage of the synchronous generator is set to be large. CONSTITUTION: A fluctuation-signal generation means 24 generates a fluctuation signal which has a predetermined frequency and which has a predetermined amplitude, it gives the signal to an automatic voltage regulator 19, and a field current is changed by the voltage regulator 19 so as to correspond to the fluctuation signal. A level-discrimination means 37 detects a fluctuation in the output frequency of a synchronous generator 7, and, when the fluctuation is at a variably set discrimination level or higher, it judges that the synchronous generator 7 operates singly. A discrimination-level setting means 35 responds to the output of a power detection means 34, and it sets the discrimination level of the level discrimination means 37 to be large as the detection power of the generated power of the synchronous generator 7 becomes large.  Thereby, it is possible to surely detect the single operation of the synchronous generator 7.

Title: Digital time base corrector
Inventor: OTAKI HIROSHI
IPC: H04N5/85
Filed: 1993-12-16
Abstract: PURPOSE:To keep an interleave relation between a luminance signal and a chrominance signal of a video signal even when the write to a memory by jitter included in a demodulated video signal is delayed when the storage capacity of the memory is reduced to nearly 1H share of the video signal. CONSTITUTION:When a read address is advanced more than a write address of an image data memory 11 and a subcarrier phase memory 17 within one horizontal scanning period, a dissidence is produced between polarity data read from the subcarrier phase memory 17 and proper polarity data latched in a latch means. After the dissidence is detected, when a color phase of read image data is inverted and data reading for a new horizontal scanning period is started and no transition to data write for the new horizontal scanning period is detected, the color phase of the image data read for the new horizontal scanning period is inverted. Thus, the interleave relation between the luminance signal and the chrominance signal of the video signal is maintained.

Title: Automobile alarming device and alarming unit therefor
Inventor: TOMITA SADAO
IPC: G08B21/00
Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To prevent an accident due to opening a door with side brake off from occurring by detecting the pull-back condition of the side brake and the opening/closing condition of the door by means of detecting switches, judging them by an alarm unit with built-in buzzer, and ringing the alarm buzzer at the dangerous condition. SOLUTION: An alarm unit circuit form 10 operates so that when a door detecting switch S2 is ON (door open), current flows in a relay input circuit RY1, a relay input circuit RY2 is ON, and current flows from a relay circuit 4 to a diode D1 or a buzzer circuit 5. At this time, in the case of a side brake detecting switch S1 being ON (a side brake is pulled), current flows in the direction of the diode D1, but in the case of the side brake detecting switch S1 being OFF (a side brake is returned), the diode D1 becomes reverse voltage or equal voltage by a precondition, current flows to the buzzer circuit 5, and the buzzer rings. Hereby, the accident due to forgetting to pull the side brake can be prevented from occurring.

Title: Method of detecting abnormal operation of magnetic disc memory system
Inventor: MARUKAMU KOORUMAN IISUTON
IPC: G11B19/04
Filed: 1988-12-19
Abstract: PURPOSE: To make possible detecting a history of abnormal operation between a head and a disk by comparing an amplitude of a repeat signal read from a track with the amplitude of the repeat signal read from another track and performing corrective operation. CONSTITUTION: The data are read from prearranged areas of respective tracks on the disk usually not being re-written while a system is operated, and a read signal is generated. When a comparison result between the amplitude of the signal read from one track 42 and the amplitude of the signal read from another track 44 on the disk shows displacement exceeding a prearranged level, a warning condition is set, and some corrective operation is performed before a real obstacle occurs in a magnetic disk storage system. That is, when a slant based on a linear relation between the amplitude of the repeat signal and a radius is without the normal range, the fact that the interface between the head and the disk is abnormal is diagnosed. Thus, the history of the operation between the abnormal head and the disk is detected.
